You can also use SYSBENCH - use that to do OLTP benchmarks, test memory speed, and cpu speed. We have seen incorrectly matched memory cause as much as a 30% slowdown in the new Intel QUADQUAD and QUADHEX Dunningtons.

We have several servers... with different RAID 10 ARRAYS, based on SATA drives, SAS (SCSI)drives, and even SSD (Solid State Memory) (Intel X25-E Extreme) drives. Some are 4 drive RAID 10, some 6 drive, and some are RAID 1. We don't use RAID 5.

I have a file somewhere where I did a bunch of comparisons but I can't find it right now. Sorry.

First of all i did mistake and i bought 1 cpu license because i believed it meant 1 server not core,
so me practically i have to buy license for 8 cores from the moment that my server is 8 x 2.26GHz, correct ?
can i install it with license of 2 or 4 cores and upgrade later if needed to 8?
Is it same software and it depends on the license or i have to install it from start ?
Thank you in advance

You can use 1 core, 2 core and 4 core license. You don't have to buy 8 core license. The core here means how many cores litespeed will use. If you buy 2 core license, litespeed will use 2 core to run. The six cores left will be saved for mysql, php and others. I am using 1 core and 2 core licenses for my servers which have 4 core CPU. Hope this helps

You can choose between 2-CPU or 4-CPU license, if you I/O wait is higher than 10%, go with the 4-CPU license. You can upgrade to 4-CPU license later if need.
The trial license is a full 2-CPU license for 15 days.

I have a Dual core Xeon server,using 1 core cpu license of litespeed, holding 1350 low traffic domains. It work great with 1 cpu license.
